GX20006 1/2" x 89" Drive Belt Replaces UC30568 for J-OHN Deer 48 inch Drive Belt D110, D120, D125, D130, D140, D155, D160, D170, L110, L111, L118, L120, L130, E170 Lawn Tractor Mower

What It Is

This is a replacement drive belt (1/2" wide, 89" long) for the mower deck of select John Deere lawn tractors. It transfers power from the engine pulley to the deck spindles to spin the blades.

Fitment & Compatibility

• Fits these John Deere models: D110, D120, D125, D130, D140, D155, D160, D170, L110, L111, L118, L120, L130, E170. Only for 48-inch mower decks – verify your deck size before ordering.
• OEM cross-reference: Replaces John Deere part UC30568. This is an aftermarket belt, not OEM.
• Measurements: 1/2" width, 89" length. Measure your old belt to confirm (length is critical).
• Check your deck type: Some 48" decks use a different belt (e.g., for 54" decks or older series). Confirm your deck model number (stamped on deck housing).

Key Things to Know

• Quality: At $11.99, it’s a budget aftermarket belt. Expect shorter lifespan than OEM (1–2 seasons vs. 3–4 seasons). Fine for light residential use.
• Installation: Moderate difficulty – you’ll need to remove the belt guard and route the belt around all pulleys and idlers per your deck diagram. A belt routing diagram is helpful (check your manual or online).
• Common gotcha: The belt can slip if tension is incorrect. Ensure the idler pulley spring is properly engaged after installation. If the belt squeals or throws, re-check routing.
• Not for zero-turns or older models (e.g., LX series, 100-series). Verify your tractor’s deck size and belt length.

Should You Buy It

Buy if you need a quick, cheap replacement for a 48-inch John Deere deck on a D100/L100 series tractor for light-duty mowing. Skip if you want OEM durability, mow commercially, or have a different deck size – invest in a genuine John Deere belt instead.
